My scheme is: 100 M /boot on ext3 (I was going to store some other info there, but its mostly "space" att)
2G swap 4G reiserfs with a complete, basic gentoo rescue install - if all goes pear shaped, I have a backup including a functioning /boot on this partition. Particularly useful with things like a gateway: you can come up on the rescue partition and provide near normal service/network access while fixing the main problem in a chroot etc. Maintenance of this partition is done offline in a chroot so other than an occasional test, its rarely run in its own right. 4G / on reiserfs with /etc, /root etc remainder (200G is below, and on my main desktop system similarly arranged I have 200G + an extra 60G drive) is all LVM containing /home, /var, /tmp and /usr. This system is mainly a LAMP server/gateway for a home network. it also contains mostly file storage and backups in /home moriah ~ # df -h Filesystem Size Used Avail Use% Mounted on /dev/hda5 3.8G 2.2G 1.6G 59% / udev 252M 2.6M 249M 2% /dev cachedir 3.8G 2.2G 1.6G 59% /lib/splash/cache /dev/vg1/usr 32G 5.9G 27G 19% /usr /dev/vg1/var 48G 2.3G 46G 5% /var /dev/vg1/tmp 16G 33M 16G 1% /tmp /dev/vg1/opt 4.0G 169M 3.9G 5% /opt /dev/vg1/home 77G 26G 52G 34% /home none 252M 0 252M 0% /dev/shm /dev/hda1 92M 18M 69M 21% /boot /dev/hda3 3.8G 1.7G 2.1G 46% /mnt/hda3 moriah ~ # There are probably performance issues, but they are not noticeable in practise. hdparm actually shows a slight speed advantage for the LVM partitions, but there are also error messages so I dont really trust it!
